Question 235035: What is the probability that a 89% foul shooter will make at least 2 shots in a basketball game?
I know it is some sort of conditional probability, but I have now idea on what formula I need to use to solve it and my book is not very helpful.

What is the probability that a 89% foul shooter will make at least 2 shots in a basketball game?
--------------------------------------
P(2<= x <=89) = 1 - P(0<= x <= 1)
= 1 - [2C0(0.89)^0(0.11)2 + 2C1(0.89)(0.11)]
---
= 1 -[0.2079]
---
= 0.7921
